it seems an extension is missing : https://www.mediawiki.org/wiki/Extension:WikiSEO
I just add this into the file composer.local.json, in the "require" array :
after adding it, run again composer to install it :
php composer.phar update
concerning tags on your page, this is because the add translation future in wikifab.org, but there are not enable on this projects.
to remove it, you have 2 solutions :
- Enable translation by installing https://www.mediawiki.org/wiki/MediaWiki_Language_Extension_Bundle#Installation
- or just remove translate tag : via you browser edit the page Form:Tutorial on your wiki ( url : /index.php/Form:Tutorial?action=edit )
search every keywork 'translatable' in the page, and just remove them.
After, you may have to edit the tutorials you already have to remove the tags, they will not be added the the future tutorials
we must find a better way to easy configure the translation behaviour.
Thanks for using wikifab, and reporting your issues.
